According to a story filed by Metro Source News:Dr. Irwin Redlener, the director of the National Center for Disaster Preparedness, says it's important to get to a shelter and stay there. Redlener says in case of a real nuclear threat, don't look at the blast, find shelter within 20-minutes, plan to stay there for at least a day or two and wait for further directions. He also recommends keeping a "go bag" packed at home, work and in your car.
